To all whom z' may concern.'

Be it known that I, FRANK Connnnr, a subject of the King of Great Britain. and a resident of Monroe, in the county of Monroe and State of l\Iiehigan, have invented a certain new and useful Brick Composition; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference heilig had to the acccmpanying drawings. and to the characters of reference marked thereon, which form a pai-tof this specification.

My invention relates to brick compositions. It particularly relates to the making of bricks which may be used for fixing blocks for securing strips, molding, panels, mop boards or the like to brick. cement or stone walls. Nails or screws may be driven or threaded into the brick-like body embodying my invention with the ease that they may be driven or screwed into wood, and moreover, they will be securely retained therein. The bricks may be placed in a wall such as a brick partition in a building, for the purpose of securing trim thereto. The bricks may be laid upon cement or other lire resisting tioors. or embedded in such iioors, and the wood flooring may be nailed thereto. The object of the invention particularly is to provide a perfect ire-resisting nonshrinkable substitute for fixing blocks of wood commonly used for securing trim and flooring, and which will form a perfect bond with masonry, brick-work or concrete, and will not be subject to shrinkage, dry rot, or decay, and which will receive and retain nails, screws, bolts or other attachments, and which will retain such fastening means as well as wooden blocks and strips commonly used in building construction.

For the purpose of illustrating the utility7 of the invention, the bricks are shown in the accompanying drawing, wherein Figure l shows a section of a partition wall in which the bricks embodying my invention are contained for the purpose of securing the trim, such as a panel board or mop board. The figures are broken views of the same wall. Fig. 1 shows a layer of bricks containing my invention and a border strip for the panel of the wall secured thereto, and

F ig. 2 illustrates a mop board which is secured by the bricks embodying my invention.

l in the figures is the wall. 2 are the bricks formed of the composition containing my invention, and 3 are ordinary tiled bricks or partition bricks of which the wall is formed. Any suitable arrangement may be made with reference to the bricks ernbodying my invention. In order to secure the mop board a tier of bricks may be laid, and in order to secure the border on the panel the bricks containing my invention may be laid on the tile bricks at the proper height. The mop board may then be secured in position by driving a nail through the mop board 4 and the plaster 5, and into the bricks 2, whereupon the mop board Will be securely retained. If desired, screws may be used. as shown, in fastening the border G of the panel. The screws 7 are passed through the border strip 6 and threaded into the bricks 2.

rI`he composition of the bricks, which have large compressional strength and at the same time are fire-resisting, and will not crumble, and yet which will receive and retain nails, screws, etc., and from which the nails and screws and bolts may be withdrawn without breaking the brick, is formed of a mixture of cinders, clinkers and cement, to which is added a certain amount of mortar coloring, such as oXid of iron, which may be in the form of colored earth or earth containing considerable oXid of iron. The mixture is rendered plastic by adding water. More specifically the composition is formed by using three prtgigound or finely brokenengii mc ers an( tiree parts of ground or iiroken clinkers. one part of colorinr earth. one part of earth containr'rgxiil in and one part of cemengt. This 1s mlxec ogether with the requisi e amount of acidulated water to render the whole plas 1c, necessary or molding purposes, such as for the making of concrete bricks. The cinders may be of any form. The preferred cinders are like those which issue forth from the smoke pipe of a railroad engine or furnace when under forced draft. Also the clinkers may be of any form, the preferred form being like those from the fire boX of an engine. It is found preferable to aeidulate the water, which
